Direct Known Subclasses:

DSEStrategy, EntBugTestStrategy, FixedNumRandomTestStrategy, IndividualTestStrategy, MOSuiteStrategy, RandomTestStrategy, RegressionSuiteStrategy, WholeTestSuiteStrategy

public abstract class TestGenerationStrategy
extends Object

This is the abstract superclass of all techniques to generate a set of tests for a target class, which does not neccessarily require the use of a GA. Postprocessing is not done as part of the test generation strategy.

TestGenerationStrategy

public TestGenerationStrategy()

Method Detail

generateTests

public abstract TestSuiteChromosome generateTests()

Generate a set of tests; assume that all analyses are already completed

Returns:

sendExecutionStatistics

protected void sendExecutionStatistics()

getFitnessFunctions

protected List<TestSuiteFitnessFunction> getFitnessFunctions()

Convert criterion names to test suite fitness functions

Returns:

getFitnessFactories

public static List<TestFitnessFactory<? extends TestFitnessFunction>> getFitnessFactories()

Convert criterion names to factories for test case fitness functions

Returns:

isFinished

protected boolean isFinished(TestSuiteChromosome chromosome,
                             StoppingCondition stoppingCondition)

Check if the budget has been used up. The GA will do this check on its own, but other strategies (e.g. random) may depend on this function.

Parameters:

chromosome -

stoppingCondition -

Returns:

getStoppingCondition

protected StoppingCondition getStoppingCondition()

Convert property to actual stopping condition

Returns:

canGenerateTestsForSUT

protected boolean canGenerateTestsForSUT()
